Abstract

Distributed Bragg reflectors (DBRs) based on chalcogenide glasses showing stopbands in the near-infrared range were designed and fabricated by thermal evaporation combined with the oblique angle deposition technique. This technique allows the deposition of alternate thin films of predetermined optical constants, leading to the fabrication of multilayer structures of tailored optical behaviour based entirely on a single glass composition. Moreover, exploratory work has been performed by determining the spectral shift of the DBRs due to chemical infiltration within their nanoporosity. These promising experimental results suggest that the chalcogenide-based reflectors can be used in the field of chemical sensing.
